Petzl's Pirana descender is one of the most popular figure eight style devices for arborists. The multiple horns on the Pirana offer a variety of braking options with varying degrees of friction. The Pirana can be installed on the rope without removing it from the harness, and thanks to the grommeted connection point, it stays in place on the carabiner to reduce risks associated with poor positioning. The Pirana helps prevent the formation of a lark's head hitch around the body and reduces rope twisting, without decreasing braking friction.
The Pirana will only accept carabiners with a diameter of 12mm. (Such as the Petzl Am'D).

The Petzl Pirana is ANSI compliant.
